Two Anti-Spall Options: Spallshield® PVB/PET Composite and Spallshield® CPET Film
DuPont™ Spallshield® PVB/PET anti-spall composite and Spallshield® CPET hard-coated PET film help stop the showering of small glass particles (called "spall") that can occur when conventional glass fails.
Traditional DuPont™ Spallshield® composite is a pre-assembled combination of PVB, PET and a hardcoat, typically used in transportation safety glass or ballistic applications where human safety is paramount. Adding Spallshield® composite during lamination increases the penetration resistance of a given thickness of glass and is also particularly useful in high-security applications.
Also available for spall protection applications is DuPont™ Spallshield® CPET, a single-component, hard-coated PET film that can be used in combination with PVB or with other high-security glazing materials. Using Spallshield® CPET film enables manufacturers to add durable spall protection to a wide range of new laminated glass designs.
